I've owned 5-series BMWs for 4 years (a new one every year) and this one is by far the best yet. It accelerates like an 8-cylinder would with same quietness and "kick" one would expect from a V-8. Handling remains outstanding and the interior comfort and fit continue to impress me. The fuel economy is not as good as my 2007 530i, but good enough to warrant a second look considering the power and smoothness. The new interior features make this one the best yet.
Push-button pre-sets for radio stations, ability to change vent settings (directional flow of air through vents) without having to go into iDrive, comfort access impressive compared to other vehicles with keyless entry, new logic-7 with HD is stupendous.
I would suggest going back to the standard auto transmission and doing away with the electronic transmission. I don't like the feel of the electronic transmission - you have to look down to see what gear you are in.
